△CAPand△TAP are equilateral and coplanar.AP¯ is a common side of the two triangles.m∠CAT=?_ (numerical answer).

Short Answer

Expert verified

The complete statement is: △CAPand △TAPare equilateral and coplanar.AP¯ is a common side of the two triangles. m∠CAT=120°.

Step by step solution

01

- Draw the diagram.

The diagram showing the given situation is:

02

- Description of step.

The equilateral triangle is a triangle in which all the three sides of the triangle are equal and all the angles are of the measure60° .

As, the triangleâ–³CAPis equilateral, therefore, in the triangle ,â–³CAP.

∠CAP=∠APC=∠PCA=60°

As, the triangleâ–³TAPis equilateral, therefore, in the triangle ,â–³TAP.

∠TAP=∠APT=∠PTA=60°

From the diagram it can be noticed that:

∠CAT=∠CAP+∠TAP.

Therefore, it can be obtained that:

∠CAT=∠CAP+∠TAP=60°+60°=120°

Therefore, the measure of the angle∠CAT is120° .

03

- Write the complete statement.

Therefore, the complete statement is: △CAPand △TAPare equilateral and coplanar.AP¯ is a common side of the two triangles.m∠CAT=120° .
